When we talk about security surveillance, almost everyone, be it manufacturers, integrators, engineers or users, more or less understands the key technologies and development trends of video surveillance, such as digitalization, networking, 1080P, 2MP, smart analytics, video summary, video compression, H.265, etc. Although these technical terms are all proposed from the perspective of technology, in the end, the project needs to be implemented, meet the user's requirements and provide specific functions. Therefore, we should think about the problem from the user's perspective, that is, we should select relevant products and technologies from the perspective of the system realizing the function and providing the value of the system. Below are five technical approaches that we will discuss together with our industry peers.
Extending storage time In security surveillance, according to GB50348 "Safety Crime Prevention Engineering Technical Specification", "The storage period of recorded data such as data, images, and voice should meet safety management requirements. All data should be stored for at least 30 days." Most users may usually adopt this storage period as the default, and some users may request a storage period of 2 months. In recent years, with the advancement of H.265 technology, the hard disk capacity of major surveillance cameras has increased to 4T, and users can request a longer storage period according to project requirements and budgets. For example, if the budget allows, you can request the storage period of surveillance footage to be 2 months or more. At the same time, compared with H.264 technology, H.265 can reduce the bandwidth by half with the same image quality, so when the demand for "extending storage time" comes up, engineers and manufacturers will naturally put more energy into H.265 technology to achieve "clearer images with the same bandwidth, smaller bandwidth with the same image". In addition, the number of hardware devices is also greatly reduced. WEILAILIFEI's wireless and POE powered security cameras have a compression capability that is about twice that of H.264+. If the image quality is the same, it can be compressed to about half the amount of H.264 data, and the security camera image is clear and smooth. In addition, the security camera set has an overwrite function that automatically erases old data and continues recording when the HDD capacity is full. Continuous recording is possible 7*24 hours a day. There is no need to manually delete recorded data.
Diverse surveillance image applications Video surveillance was initially mainly used for security surveillance, but later various applications such as road surveillance, public security surveillance, and factory production surveillance emerged. Nowadays, the number of pixels in a camera is no longer an issue, and there are 2 million pixels, 3 million pixels, 5 million pixels, etc. WEILAILIFEI's wireless and POE powered security camera is a high-resolution security camera with 3264 x 2488 resolution, ensuring the safety of people and homes 24 hours a day, 365 days a year. You can see everything within 24 meters even at night. At present, high-definition surveillance footage is transmitted from the front-end to the back-end platform, but the problem is not only security surveillance, but also how to effectively integrate it into the user's business, save labor costs through unmanned surveillance, reduce labor costs through video patrols, and utilize it in various ways. Therefore, when the demand for "diverse surveillance image applications" comes out, engineers and manufacturers will naturally increase the use of smart analytics technology and try to maximize the role of smart analytics technology in combination with the user's business.
Improving system operation Currently, many organizations use a large number of surveillance cameras, some even exceeding 1,000. In the traditional approach to system operation, it is difficult for security staff at the monitoring center to monitor the entire system in real time. Usually, the video can only be played back when an accident occurs, but it is unclear whether the played video is available. If another accident occurs in the same time period, the video needs to be examined again, which creates a vicious cycle. In addition, I think everyone has seen detective dramas and TV series, but detectives often spend several hours or even more time to find evidence. If such scenes are applied to the monitoring center of an enterprise or organization, security staff will be confused or have difficulty achieving the expected effect. Therefore, if there is a demand for "improving system operation", engineers and manufacturers will focus on technologies such as video summary, video quality diagnosis, and aim to develop the entire security system towards true smartness. Only one LAN cable is needed between WEILAILIFEI's POE security camera and the recorder, and the security camera itself does not need power. No complicated settings are required, and all security cameras are set up when the operation test is carried out. When you connect it to your PC or TV monitor, the image will be displayed automatically and recording will start. You can start recording without any settings, so it is easy for beginners to use.
Compatibility with major manufacturers' products When we first talk about the compatibility of security surveillance products, we usually hear words such as "our products support the ONVIF standard...", but when we touch on specific projects, we often find that products from different brands are not actually compatible. With the emergence of GB/T 28181 "Technical requirements for information transmission, exchange and control of security video surveillance network systems", guidance was provided to point out the compatibility of security products from different brands, but in actual operation, the compatibility problem remains unsolved. Therefore, in large-scale projects, it is recommended that users take the initiative to make use of the strengths of each company and make the security surveillance system truly IP-based. To take a simple example, both computers and laptops with network interfaces can connect to the Internet. Therefore, a truly IP-based surveillance camera does not depend on a specific brand, and any IP camera should be able to connect to the security system. Ultimately, many companies in security products will focus on certain areas such as cameras, storage, and surveillance platforms. Therefore, if there is a requirement for "compatibility with major manufacturers' products", manufacturers will naturally seriously consider the compatibility of ONVIF, GB/T 28181, otherwise they will eventually be eliminated. In order to continue to provide stable, high-quality products, WEILAILIFEI strictly controls quality control, production management, inspection, etc. at the factory.
More convenient device wiring
At present, surveillance cameras usually require a power cable and a network cable, but the industry wants to use one cable to solve this problem (i.e., use POE power supply), or adopt wireless transmission. However, wired transmission is more stable than wireless transmission, so we do not recommend the wireless transmission method unless necessary. Nevertheless, the main reason why POE power supply is not widely used is that POE power supply is unstable and the reliability of products needs to be improved. Therefore, when the demand for "more convenient device wiring" comes out, manufacturers naturally improve their POE products, security manufacturers improve their POE- supplied surveillance cameras, and switch manufacturers improve their POE switches. At the same time, this promotes the development of wireless transmission technology, because in some projects, the renovation work is very difficult or the distance is particularly far, and the wireless transmission method can solve the problem. WEILAILIFEI's LAN cable has a waterproof connector, so the LAN connection part will not get wet in the rain even if the POE camera is installed outdoors. You can use this security camera set with peace of mind.
Through these innovative ideas, WEILAILIFEI will continue to strive to provide smarter and more convenient video surveillance solutions.
